Title: Toll charging arrangement for coin-box telephone
IPC: H04M17/02
Filed: 1971-11-11
Abstract: 1355224 Coin-freed telephone system INTERNATIONAL STANDARD ELECTRIC CORP 11 Nov 1971 [17 Nov 1970] 52377/71 Heading H4K  Coin collection pulses are derived at a prepayment substation from the incoming meter pulses by digitally determining the spacing between the meter pulses and dividing this value by the fee unit to produce a one cash unit pulse which is then multiplied by the value of the smallest depositable coin. In the circuit arrangement shown the arriving metering pulse TT is applied to an evaluating stage 2 which produces outputs on A, B and C following receipt of first, second and third metering pulses. The output of clock pulse generator T passes through gate 5 and is counted by counters 3 and 4 between successive metering pulses. The fee unit is set in tariff code unit 7 which produces an output fed to gate 6 so that whenever the count in counter 3 equals the value of the fee unit a pulse is sent to counter 8 and counter 3 is reset. When an output on B is present the contents of store 8 will be transferred to store 10 on the arrival of a metering pulse and compared with the count in counter 4. If these are equal a pulse representing the cash unit is transmitted through gate E and stored in counter 12 until this count equals the smallest coin code provided by stage 14 when a pulse appears on line L and passes through OR gates 16 and 30 to the debiting unit. Provision is made to use clock pulses T to provide a plurality of coin collation pulses on the arrival of the first metering pulse so that the minimum call fee is colluted. Subsequent collution pulses can be delayed to account for the amount of the coins colluted perhaps exceeding the call fee due and additional pulses can be provided if, owing to this delay too little money is colluted. When coin collution pulses and metering pulses coincide the internally generated pulse is suppressed and the latter used. In fault conditions a minimum fee can be colluted both by the appearance of signal A and signal B.

Abstract: 1,242,155. Masted lift trucks. CLARK EQUIPMENT CO. 30 Oct., 1969, No. 53155/69. Heading B8H. A side loader attachment 20 for a lift truck is provided with stabilizing devices 102 which, when the truck is operating in an aisle between storage racks, are operable to engage upper and lower surfaces of the racks 34 to stabilize the truck during the insertion or removal of a load in a rack. As shown, sleeve members 40, supporting the side-operating reach mechanism and removably supported on the forks 30 of the truck, are each provided with a pair of stabilizing devices 102. Each device 102 comprises a member 104, provided with storage rack engaging plates 114, 116, and a member 106, provided with a rack-engaging plate 130, the two members 104, 106 being pivoted at 108 to a bracket secured to the sleeve member 40. In operation, the plates 116, 130 of a device 102 at one side of the truck are brought into engagement with the bottom and top of a storage rack 34 by means of an hydraulic ram 136, and the plate 114 of the device at the other side of the truck is brought into engagement with the top of a rack 34 at the other side of the aisle. In a modification, Figs. 9, 10 (not shown), the members 104, 106 of each device 102 are replaced by a single bell-crank lever having a pair of rack-engaging plates, the arrangement being such that one of the plates engages the bottom of a rack at one side of the truck and the other plate of the corresponding device at the other side of the truck engages the top of a rack. When the devices 102 are engaged with a storage rack and the load support 66 of the reach mechanism is located beneath a load L, actuation of the rams of the devices 102 causes the load support to be raised into engagement with the load. The load support 66 is movable relatively to an intermediate frame 52 which is movable relative to the frame of the attachment by hydraulic rams 78, Figs. 3-5 (not shown), and can be extended to either side of the truck.

Abstract: 1,174,574. Tractor power lift mechanisms. DOWTY HYDRAULIC UNITS Ltd. 21 March, 1967 [22 Dec., 1965], No. 54366/65. Heading AlP. [Also in Divisions E1 and F1] A tractor power lift mechanism incorporates a fluid logic device to control an attached implement. The mechanism provides visual, position, and draft control, the lever 30 operating a rotary valve 68 to select either position or draft and the lever 31 being movable in one direction for visual control and in the other direction for setting the position or draft. The valve 68 connects into the hydraulic circuit either a position feedback regulator 26 via lines 51, 52 or a draft feedback regulator 28 via lines 53, 54. Each of these regulators has two valves, one associated with each line, which can be closed or opened to exhaust by movement of the lever 31 or by a position control cam on the rockshaft acting on lever 25 or by a draft sensing link acting on rod 27. The Control Circuit. A pump 42 supplies pressure fluid to a spool valve 45 which is controlled by a fluid logic device 61 to supply and exhaust fluid from the lifting ram via line 47. A pump 48 supplies the device 61 which includes a mono-stable circuit 77 with supply 78 feeding reservoir via duct 80 when there is a pulse at A in conduit 79. This occurs when both valves in the regulator 26 (or 28) are closed. The bistable circuit 83 then has a pulse at A in duct 85 which deflects the flow from supply 84 along the lower wall until it reaches duct 89, which, in this condition, is pulsed to deflect the flow around island 91 to the reservoir duct 98, the spool valve being held by springs in a neutral position to lock fluid in the ram. If the regulator is moved to require a lifting movement from the ram the pulse at A is cut off which operates circuit 77 to provide a pulse at C in conduit 88 to switch the circuit 83 to supply fluid in conduit Y to the spool valve to bias it into the lift position. For lowering, the pulse at A is operative but the pulse at B is cut-off whereby fluid is directed into conduit X to bias the spool valve into the "lower" position. For visual control the lever 31 is moved to shift valve 36 whereby fluid is suppled to nozzles N 1  and N 2  which operate to control the circuit in a similar manner to the valves in the regulators but do not have feedback control.

A draughting machine has a ruler indexing mechanism comprising a slider c on which a trigger h is pivotally mounted, the slider being movable in a channel in a bed b and the trigger having a position in which it is fixable to the bed. Lugs d of the slider support an axle e of the trigger and an arm p of a member l passes through holes q and # in a cover plate a and the slider c respectively. The other arm m of the member l is located in a pivoted pawl o which engages the teeth of a plate k. A knob t covers the mechanism and enables rulers associated with the device to be set at given angles. Thumb pressure on the trigger above the axle e causes an arm of the trigger carrying a lug g to be pressed against the slider, thus moving the slider inwardly and lifting the pawl out of engagement with the plate k so that the knob can be turned. On releasing the thumb pressure, a spring s returns the slider to its original position and the pawl relocks the knob. With thumb pressure applied below the axle e, the slider disengages the pawl from the plate k but the lug g enters a hole i in the bed so that the pawl remains in its disengaged position on releasing the thumb pressure.
